The embodiments of the invention provide a reference signal sequence transmission method and a piece of equipment. The method comprises the following steps: user equipment receives configuration information sent by a base station, wherein the configuration information is used to indicate a first basic sequence group allocated by the base station for the user equipment, the configuration information is generated by the base station based on a division mode of basic sequence groups in a communication system where the base station is located, the division mode divides the basic sequence groups in the communication system into multiple basic sequence sets, each basic sequence set contains at least one basic sequence group, at least one of the multiple basic sequence sets contains at least two basic sequence groups, and a first basic sequence set to which the first basic sequence group belongs is one of the multiple basic sequence sets; the user equipment determines a first basic sequence set according to the configuration information; and the user equipment generates a reference signal according to the first basic sequence set, and sends the reference signal to the base station.
